Data Sufficiency (Numerical Ability) Strategies

Learn core concepts, essential formulas, and attempt practice questions designed on the latest TCS NQT testing patterns.

Key Concepts & Formulas

  • 1Do not compute the final value unless asked; check if equations can be formed.
  • 2Options setup: A) Statement 1 alone is sufficient, B) Statement 2 alone is sufficient, C) Both together are needed, D) Neither is sufficient.

TCS NQT Style Practice Questions

Practice Question 1

What is x? (1) x + y = 10 (2) y = 4.

A) 1 alone sufficient
B) 2 alone sufficient
C) Both together sufficient
D) Neither sufficient

Correct Answer: C) Both together sufficient

Step-by-step Solution: From (1) alone, x has infinite values. From (2) alone, x is unknown. Combining both: x + 4 = 10 => x = 6. Thus, both statements together are sufficient.

Practice Question 2

Is x positive? (1) x^2 = 16 (2) x^3 = 64.

A) 1 alone sufficient
B) 2 alone sufficient
C) Both together sufficient
D) Neither sufficient

Correct Answer: B) 2 alone sufficient

Step-by-step Solution: From (1), x can be 4 or -4 (insufficient). From (2), x must be 4 (positive, sufficient). Hence, statement 2 alone is sufficient.

Study Pro-Tip

Check each statement independently before attempting combinations logic.
